N2 - This study was conducted to determine the effect of rosemary or lemongrass herbs at 10 g daily on feed utilization, milk production, milk composition, and fatty acid profile in lactating Damascus goats. Fifteen goats were divided into 3 treatments (5 goats each) and fed a basal diet of berseem clover and concentrates (1:1 on dry matter (DM) basis; Control treatment) or the control diet supplemented with either 10 g daily of rosemary (Rosemary treatment), or 10 g daily of lemongrass (Lemongrass treatment) for 12 weeks. Inclusion of lemongrass and rosemary did not affect (P > 0.05) nutrient intake. However, inclusion of lemongrass or rosemary increased (P < 0.05) organic matter and fiber digestion. Ruminal pH was not influenced (P > 0.05) by dietary treatment. Feeding lemongrass or rosemary treatment increased (P < 0.05) ruminal concentration of short chain fatty acids, propionate, and serum glucose concentration and decreased serum cholesterol concentration. Feeding lemongrass or rosemary treatment increased (P < 0.05) milk production (actual and energy corrected milk), and milk fat and lactose concentration. Feeding rosemary or lemongrass containing diet increased (P < 0.05) total unsaturated fatty acids and total conjugated linoleic acid and decreased total saturated fatty acids (P < 0.05). In conclusion, supplementation of lemongrass and rosemary in the diet of lactating Damascus goats at 10 g/goat daily enhanced nutrient digestibility and milk yield, with positive ruminal fermentation.
